What Factors Affect the Energy Converted to Heat in Radiant Heating Systems?

[AnnVole]

I wish to design several systems of radiant heating that use both transfer of heat and friction heating of the transfer fluid which will be some grade of oil (which can handle a wide temperature range and has reduced equipment wear). What I need is to know is the energy turned into heat given the variables of viscosity, flow, pipe size, and pipe length. I will use computer software to convert temperature changes to viscosity changes (not linear). I will assume the system will remain in laminar flow.

The energy converted to heat depends on several factors, including the viscosity of the oil, flow rate, pipe size, and pipe length. The viscosity of the oil affects its ability to transfer heat, with more viscous oils transferring less heat per unit area, while less viscous oils transfer more heat per unit area. The flow rate will also impact the amount of heat transferred; higher flow rates will transfer more heat than lower flow rates. The pipe size and length also affect how much heat is transferred; longer and larger pipes will transfer more heat than shorter and smaller pipes. To calculate the energy converted to heat, you will need to use a heat transfer equation, such as the Fourier's law of heat conduction. This equation takes into account the properties of the oil, the flow rate, pipe size, and pipe length, and can be used to calculate the energy converted to heat given these variables.
